.MACHINE FOR THE PRODUCTION OF PAPER TUBES.-

' Specification of Letters Patent.

Patented April '7, 1908.

Application filed August 5, 1905. Serial No. 272,910.

To all whom it may concern:

Be it known that I, JEAN GoHY, subject of Belgium, residing at Ensival,near Verviers, in the Kingdom of Belgium, have invented new and usefulImprovements in Machines for the Production of Paper Tubes,

the following is a specification.

This invention relates to a machine for the production of paper-tubessuch as are, for

of which example, used under the name of coptubes TEL for splnning orweaving purposes. The shapewhich must be imparted to tubes of this kindvaries within fairly wide limits and is in some cases cylindrical, inother cases more or less conical, according to the purpose for which thetubes are required. Hitherto these tubes have been produced by means ofmachines, each of which was constructed to turn out a special type orpattern of tube, this being due to the fact that for producing each typeor pattern sheets of paper of a certain shape must be used, and thevariations in the shape of the paper involve variations in the action ofthe machine.

Thus, for instance, for the production of a cylindrical tube one edge ofa sheet of paper can be directly applied to the mandrel on which thetube is to be rolled, whereas in the case of a conical tube the shape ofthe paper necessitates, in the machines hitherto known, a certain amountof rotation of the sheet in order to place the paper on the mandrel inthe desired position, and the paper must in some cases be fed to thepoint of the conical mandrel and in other cases to the base of thelatter. The machine must be specially constructed for this purpose andmust be provided with special paper-feed mechanism which involves thesliding of the paper in such a manner that a large amount of loss occursthrough tearing, more particularly if the sheets have to be fed to thepoint of the mandrel.

In many cases tubes have to be manufactured from sheets of paper theborders or edges of which have been scraped and thus reduced inthickness to facilitate the pasting of the tubes; in such cases it isnot possible to introduce the paper edgewise into the slot or groovewith which the mandrel is provided, and the paper must be introducedaccording to a line of section in its plane, and for this purposerotation is required in order to apply the edge of the paper to thestationary mandrel.

The object of the present invention is to remove these disadvantages andto provide a machine of comparatively simple and compact construction bymeans of which papertubes of any type or pattern used in ractioe can beproduced, that is to say, cy indrical tubes or tubes which are more orless conical, the said tubes being manufactured from a strip or band ofordinary paper or paper with scraped edges, and the said paper being inall cases introduced at the base. of the mandrel. These results areobtained by making certain parts of the machine adjustable and byexchanging certain parts when necessary, for instance mandrels knivesand gear-wheels, the principal parts of the mechanism remaining,however, unaltered during the manufacture of tubes of all kinds. As inthe case of the machines hitherto known the improved machine comprises apaper-feed mechanism, a device or devices for cutting the paper, andmechanism for forming the tubes. An important difference lies, however,in the fact that the relative positions of the paper-feed mechanism andthe tube-forming mechanism can be altered at will by means of simpleadjustment, so that the paper can always be fed to the mandrel by meansof a simple rectilinear movement, with a single angular displacement. Inpractice the altering of the relative positions of the parts referred tois preferably effected by arranging the tube-forming mechanism on atable or platform which is adjustable in the machine frame and which isalso rotatable about its own central axis, so that the mandrel can bebrought into any desired angular position with regard to the paper.

The invention is illustrated, by Way of exam Is, in the annexed drawing,in which igure 1 is a plan-view showing the principal parts of themachine in the position which they occupy for the manufacture ofcylindrical tubes from paper the edges of which have been made thin inorder to facilitate pasting. In this figure the tube-forming mechanismis only diagrammatically indicated in order not to unnecessarilycomplicate the drawing. Fig. 2 is a side-view, in partial section,showing the main driving shaft, the paper feed rollers and the mechanismfor controlling the knives; the tubeforming mechanism not being shown inthis figure. Fig. 3 is a side-view of the frame supporting thefeed-mechanism. Fig. 4 diagrammatically illustrates the arrangement ofthe feed-rollers and guide-rollers by means certain types of conicaltubes.

of which the p%per is supplied to the cuttingmechanism. ig. 5 is afront-view of two feed-rollers. Fig. 6 is a front-view illustrating thetube-forming mechanism comprising a guide, a mandrel, a paste-brush, adevice for pressing together the pasted edges of the rolled sheets, anda device for removing the finished tubes. Fig. 7 is a side-view of themechanism shown in Fig. 6, seen from the left, and Fig. 8 is a similarview seen from the right. Fig. 9is a plan-view of the mechanism shown inFig. 6. Fig. 10 is a horizontal section on the line AA of Fig. 7 showingmore particularly the arrangement which allows of controlling theangular position of the mandrel with regard to the paper-feed mechanism.Fig. 11 is a front-view of the ripper belonging to the tube-forming mecanism, shown in Figs. 6 to 9. Fig. 12 is a planview of Fig. 11 showingthe arrangement used for rotating said gripper. Fig. 13 is a side-view,in partial section, of the mechanismshown in Fig. 11. Figs. 14 and 15are respectively an elevation and a plan-view of the mechanism used foroperating one of the knives; in these figures the mechanism is shown inconnection with a straight knife. Figs. 16 and 17 are an elevation andplan view respectively illustrating the knife-operating mechanism inconnection with a curved knife such as is used for the manufacture ofFig. 18 diagrammatically illustrates the ositions of the tube-formimmechanism and paper-cutting mechanism urin the manufacture of conicaltubes with he ically twisted outer edges.

As shown in Figs. 1 and 2 the machine comprises a-frame 1 which supportsa .plate or table 2. The entire surface of the latter is slotted in themanner indicated, in Fig. 1, at3, the purpose of the slots being toallow of adjusting the mechanism in different positions on the table.Bearings 4 fixed to the table 2 support a main-shaft 5 which is adaptedto be driven by means of a ulley 6 and which drives, by means of beve-gear 7 and 8, a shaft 9 arranged in suitable bearings 10. A toothedwheel 11 on said shaft 9 meshes with a toothed wheel 12 fixed to one endof a shaft 13 mounted in bearings 14. To the other end of the shaft 13is fixed a clutch 15 adapted to cooperate with a clutch 16 which isaxially movable on a shaft 17. The latter is supported by suitablebearings and extends through practically the entire len th of themachlne. A collar 18 is fixed to 516 clutch 16 and is engaged by theforked part 19 of a lever 20 pivoted at 21. The

- ever 20 is adapted to be operated, from either end of the machine, bymeans of suitable transmission-gear 22; the latter is diaammaticallyindlcated in Fig. 2. The shaft 17 serves for operating the differentsets of mechanism which the machine comprises. For this purpose the saidshaft is provided with gear-wheels 23, 25 and 26 and with cams 29 and30. The gear-wheel '23 drives the paper-feed mechanism, which isdiagrammatically indicated by 24 in Fig. 1. The tube-forming mechanismdiagrammatically indicated by 27 and 28 is driven by the gear-wheels 25and 26, and the cams 29 and 30 serve for operating the paper-cuttingmechanism 31 and 32, the latter being shown, in Fig. 1, in the positionoccupied during the manufacture of cylindrical tubes from a strip ofpaper, the edges 34 of which have been scraped or thinned to facilitatepasting. Paper-feed mechanism of any suitable construction can be usedif, as in the example illustrated, the adjustment of the relativepositions of the feedmechanism and tube-forming mechanism is solelyeffected by displacing the latter.

The paper feed mechanism illustrated comprises a roller 35 (Fig. 2)having bearing in brackets 36' fixed to the frame 1. The paper web 33coming from this roller passes over a guide-rod 37 supported bystandards 38 fixed to the tab-le2. From the rod 37 the paper-web passesto the feed-rollers 39 and 40. The roller 39 is positively driven bymeans of suitable mechanism, whereas the roller 40 serves merely as apressure or guideroller. From-the rollers 39-and 40 the paper passes tothe narrow plates 41 and 42, fixed to rods 43, which plates form guidesand extend into grooves 44 provided in rollers 45 and 46. The roller 45is positively driven and the roller 46 serves as a pressure-roller. Thesurfaces of the rollers 39, 40, 45 and 46 are not smooth but areprovided with grooves 44 (Fig. 5) of suitable depth, which preventirregular displacement of the paper.

The feed rollers 39 and 45 are intermittently rotated by means of thegear-wheel 23 already referred to. For this purpose only a segment ofthe circumference of the said wheel is toothed, as shown in Fig. 2, sothat during a portion of the period of rotation the paper-web isstationary in order that it can be cut and applied to the mandrels. Thewheel 23 operates a bevel-wheel 47 mounted on a shaft 48 carried by abearing 49 adjustable in a slot 50 in a frame 51, the bearings of therollers 39, 40, 45 and 46 being also arranged in the said frame 51. i

The shaft 48 carries, outside the frame 51, a toothed wheel 52connected, by means of a toothed wheel 53, with a pinion 54 at one endof the axle of the roller 39. The bearings of the roller 40 are slidablein slots 55 in the frame 51, and the said roller rests freely on theroller 39. The pinion 54 is connected by means of a toothed wheel 56with a pinion 57 fixed to the axle of the roller 45. The bearings of theroller 46 are slidable in slots 58 in the frame 51. Each time therollers 39, 40, 45 and 46 are rotated by the action of the toothedportion of the bevel wheel 23 the fixed by means of a set screw 61.

papenweb 33 is moved through a certain istance and passes between theguide-plates 41 and 42. The length of the latter varies according to theposition of the first cuttingdevice 31, by which the paper is supportedafter leaving the guides as will be described hereinafter.

Two cutting devices 31 and 32 are shown in Fig. 1, but a larger numbercan be provided if the nature of the cutting operation required rendersit desirable. As regards the knives used, these can be of any suitableknown kind, the cutting operation being effected in the ordinary knownmanner. Since the cutting-devices must be adapted to be adjusted on thetable 2 in any desired position, by means of the slots 3, according tothe manner in which the paper-web is to be cut, arrangements must bemade to allow of operating the said devices in all ositions by means ofthe cams 29 and 30 fixed to the shaft 17. The means adopted for thispurpose are shown in Figs. 14 to 17, which represent two different kindsof cutters. Each of the cutting devices comprises a sup ort 59 adaptedto be bolted to the table 2' with the aid of the slots 3 and eachsupport 59 carries a rotatable vertical shaft 60 adapted to be To thehead 62 of the shaft 60 is bolted an angularly bent arm 64, and a secondarm 66 is pivoted at 65 to the said head. To the arm 66 a plate orsupport 68 adapted to cooperate with the arm 64 is adjustably connectedby means of'bolts and nuts 67 the arm 66 being integral with a curvedarm 69, to the end of which is pivoted, at 70, a link 71 which ispivotally connected at 72 to a sleeve 73 ada ted to slide on the shaft60. A spline 74 ormed on said shaft 60 engages the said sleeve 73, whichis provided with a groove or reduced portion 75 into which engage twopins 76 fixed to the end of the forked part 77 of a lever 78 pivoted at79 to an arm 80. The latter is fixed to a sleeve 81 the position ofwhich on the shaft 60 is adjustable by means of a set screw 82. Thelever 78 carries a block 83, the position of which is adjustable bymeans of a set screw 84 and which is provided with a roller 85 adaptedto coperate with one of the cams 29 or 30 mounted-on the shaft 17, thesaid roller 85 being held in contact with the cam by means of a spring86 which is connected to the head 62 and sleeve 73 in such a manner thatit tends-to make the latter ascend.

When the operative cam-surface abuts against the roller 85 the latter israised and the sleeve 73 is moved downwards on the shaft 60. The link 71is thus caused to exert a ull on the movable arm 66, which carries affnife. It is obvious that owing to the connection between the groove 75and the arm 70, which can be adjusted at any desired angle with regardto the head 62, it is not essential that said head and the lever 78should be in the same vertical plane in order to operate thecutting-device. If the sleeve 81 is rotated on the shaft 60 the pins 76slide in the groove 75, so that the arm 78 can always be brou ht intodirection perpendicular to the sha t 17 The cam 29 or 30 can therefore,always operate the cutting-device, whatever position is given to thehead 62 in order that the paper may be cut in the direction desired.

In Figs. 14 and 15 the cutting-device is shown in connection with aknife used for cutting the paper longitudinally at the center of theband, for the manufacture of cylindrical tubes. Fig. 1 illustrates theposition of this knife and the operating gear, with regard to the paperto be cut. It will be seen that the cutting device is arranged laterallywith regard to the paper band 83. The arm 64 is provided with adownwardly bent portion 87 in order to give passage to the guide orgripper of the tube-forming mechanism, as will be hereinafter described.A rectangular portion or blade 88 of the said arm extends underneath thepaper and supports the latter longitudinally, in the direction of itsaxis. The arm 68 fixed to the movable arm 66 carries a knife 89 adaptedto cooperate with said blade 88 for the purpose of cut ting the paper.When the cam 30 acts on the roller 85 the knife 89 is depressed and cutsthe paper along the edge of the blade 88 (Figs. 1, 14 and 15). Ifcylindrical tubes are to'be produced from a paper-band, the

' edges 34 of which have beenscraped or otherwise reduced in thickness,the paper must .not only be cut longitudinally by the knife 89, but mustalso be cut transversely. For this purpose a second cutting-device isprovided, which is adapted to be operated by the cam 29 and which issimilar to the one already described, except with regard to theoperative parts connected to the head 62 and 7 arm 66. As shown in Fig.1 the fixed head 62 carries a straight plate 90 which serves as I asupport for the paper leaving the guides 41 and 42, and the movable arm66 carries a knife 91 adapted to cut the paper, by being depressed. Inorder to obtain sufficient friction between the parts 90 and 91 themovable arm 66 may be acted on by a spring 92 (indicated in Fig. 15, andshown, also, in Fig. 17) which spring tends to move the arm 66 towardsthe part 62 and thus insures a certain amount of friction between theparts .90 and 91, similar to that which occurs between the blades of apair of scissors. It will be understood that the shape of the kniveswith which the cuttin devices are provided may vary within wi e limits,according to the type or pattern of the tubes to be produced.

The two forms of construction described are suitable for cutting paperin the form of two rectangular parts 93 and 94 (Fig. 1) for theproduction of cylindrical tubes from paper within thin edges. Theposition and shape of the knives or blades vary in accordance with theshape of the tubes to be produced. For producing, for example, a highlyconical tube with a helically twisted pasted edge, the paper must, as isknown, be cut in the manner indicated in Fig. 18, that is to say twotriangular parts 95 and 96 with curved edges 97 and recesses 98 must becut out of the paper-band. For this purpose knives of the known shapeillustrated in Figs. 16 and 17 are used. As shown in these figures, thehead 62 ,is provided with the fixed, curved blade 99, and the movablearm 66 carries the movable blade 100, the curvature of which correspondswith that of the blade 99. The blade 100 carries at its end a smallsupplementary knife 101 adapted to cooperate with a recessed blade 102for the purpose of producing the recesses 98 at the apices of thetriangles 95 and 96. For cutting out the triangles 95 and 96 threecutting-devices 103, 104, and 105 are used, arranged in the manner shownin Fig. 18; the devlces 103 and 104 comprise curved knives similar "tothose shown in Figs. 16 and 17, and the device 105 comprises knives ofthe kind shown in Figs. 14 and 15, that is to say, provided with astraight blade 89 and a fixed blade 88 carried by angularly bentsupports having approximately the shape shown in Figs. 14 and 15 inorder to give assage to the guide or gripper which feeds t e cut paperto the tube-forming mechanism. Generally speaking, therefore, the knivescan have any desired shape, the arrangement of the cutting devices beingsuch that the said knives can be operated whatever position is occupiedby the head 62, with regard to the operating mechanism, and the lever78.

The construction of the tube-forming mechanism will now be describedwithout at present entering into details with. regard to the manner inwhich the said mechanism cooperates with the cutting-devices and thefeedmechanism. It will then be explained how the special constructionand arrangement of the difierent parts allows of producing, in a singlemachine, tubes of different patterns and types with the aid of simpleadjustment and variation of the relative positions of thecutting-devices and feed-mechanism.

As has already been mentioned, each tube forming mechanism is operatedby means of one of the bevel-wheels 25 and 26, the latter being arrangedin any suitable position on the shaft 17. Each of the said bevel-wheelsoperates a bevel-wheel 106 fixed to a shaft 107 (Fig. 1) of suitablelength, mounted in bearings 108, the latter being fixed to a frame 109secured by means of screws, and the slots 3 to the table 2. Each of theframes 109 supports a circular plate 110 which is provided with twoslots 111 (Fig. 10) and on which is mounted a frame or table 112supported by four blocks 113 arranged in pairs diametrically oppositeeach other; two of the said blocks 113 are provided with screw-threadedrods 113 extending through the slots 11.1 in such a manner that the saidblocks can be fixed to the plate 110 by means of nuts 114. The other twoblocks 113 rest freely on the plate 110 and merely'serve as supports forthe table 112. The latter can thus be, arranged in any desired positionwith regard to the plate 110. Each of the frames 109 is so arrangedthatthe res ective shaft 107 is perpendicular to the sha't 17.

For altering the position of the table 112 it is sufficient to unscrewthe nuts 114 and to displace the screw-threaded rods 113 in the slots111. It will be shown hereinafter that this arrangement is highlyimportant for the purpose and action of the machine. To each shaft 107there is fixed a bevel-wheel 1 1 5 which meshes with a bevel-wheel 116fixed to vertical shaft 117 arranged in suitable bearings concentricallywith the plate 110. Above'the table 112 the shaft 1 17 is provided witha bevel wheel 118 (Figs. 6, 8. and 9) which meshes with a bevel-wheel119 (Fig. 9) fixed to a horizontal shaft 120 supported on the table 112by means of bearings 121 and 122. At the sides of the bevel-wheel 119there is arranged a wheel 123, a portion of the circumference of whichis toothed (see Fig. 8). The wheel 123 is provided with a curved plate124 andthe toothed portion thereof meshes with a toothed pinion 125(Figs. 6, 8, 9) mounted on a small shaft 126 arranged in bearings 127.The wheel 125 is fixed to a cam 128 (Fig. 8) which is provided with acircularly curved surface 129 of the same radius as the plate 124, sothat when the toothed part of the wheel 123 is moved out of engagementwith the pinion 125 the surface 129 of the cam 128 comes into contactwith the rojecting plate 124 and thus locks the sha t 126. To thelatter, which thus receives intermittent movement, there is fixed agear-wheel 130 which mesheswith a small gear-wheel 131 mounted on anaxle 132 (Fig. 9) supported by bearings 133 on the table 11.2. The saidaxle 132 carries a socket or chuck 134 (Fig. 6) into which is fixed acylindrical or conical mandrel 135, the length of which depends on thelength of the tubes to be produced.

It will be understood from the above description that the rotation ofthe shaft 107, which operates the tube-forming mechanism, imparts to themandrel 135 intermittent rotation by means of the gear-wheels 118, 119,123, 125, 130 and 131,the said mandrel being kept stationary, during theintervals between successive movements, by the looking of theintermediate shaft 126 due to the contact of the cam-surface 129 withthe plate tity of paste, which it 124 fixed to the wheel 123. The numberof revolutions performed by the mandrel 135 during each movementdepends, of course, on the number of teeth with which the wheel 123 isprovided, and on the ratio of the gearwheels by means of which themovement is transmitted.

The table 112 supports, independently of the mandrel 135 and operatinggear described, a vessel 136 of suitable size containing the adhesivesubstance which is required for pasting the tubes formed on the mandrel.In the Vessel 136 there is arranged a plate or trough 137 carried by anarm 138 which is rotatable, by means of a sleeve 139, on a rod 140carried by a bracket 141 fixed to the table 112. To an extension 142(Fig. 7) of the arm 138 is attached a spring 143 connected with an arm144 which is also carried by the table 112. This spring exerts a pull onthe end of the rod or extension 142 and thus tends to raise the plate ortrough 137 and to keep the arm 138 in contact with a cam 145 mounted onthe shaft 120. During the rotation of the latter the said cam 145 depresses the arm 138, which is raised again by the spring 143 when thecam has cleared the arm. The plate or trough 137 is thus alternatelyraised and lowered, so that during each revolution of the shaft 120 acertain quantity of paste is transferred from the vessel 136 to a brush146 (Figs. 6 and 7) mount ed on a shaft 147 which is rotatable in asupport 148 on the table 112. To the said shaft 147, which is shownseparately in Fig. 9, without the brush 146, there is fixed outside thebearing 148 a sprocket-wheel 149 gearing with a chain 150, which assesover a sprocket-wheel 151 mounted on the shaft 120, so that during eachupward and downward movement of the plate or trough 137 the brush 146operated by the shaft 120 and the chain 150 is supplied with a certainquanapplies to the paper on the mandrel 135. The vessel 136 alsocontains a pressing device 152 Figs. 6 and 9 arranged below the mandrel.135 and carried by a lever 153 which is similar to the lever 138 and isalso rotatable on the rod 140 by means of a sleeve 154. The lattercarries a rod 155, which is acted on by a spring 156 in such a mannerthat the lever 153 is kept in contact with a cam 157 on shaft 120 sothat the rotation of said shaft causes the device 152 to be depressedand removed from the mandrel until the cam has cleared the lever 153,whereupon the spring 156 moves the device 152 back towards the mandrel.The action of this part of the mechanism will be understood from theabove description. The paper is fed to the mandrel by means of mechanismwhich will be described hereinafter,

one edge of thev paper being inserted into a groove 158 which lies inone of the generators of the mandrel and is in alinement with a slot159' (Fig. 6) formed in the bearing 133 and the socket or chuck 134which sup orts the mandrel. The aper thus applied to the mandrel isrolled round the latter when the toothed portion of the wheel 123 mesheswith the gear-wheel 125. Simultaneously the r0- tation of the shaft 120causes the brush 146 to be operated by the chain 150 and is suppliedwith paste by the plate or trough 137.

The brush transfers the paste to the paper, so that the latter is pastedwhile being rolled and can be subjected to slight pressure by means ofthe device 152 when the tube has been produced and the rotation of themandrel has ceased. l/Vhen the ressing device is lowered by the actionof t e earn 157 the tube is finished, the rotation of the mandrel beingprevented by the locking action of the surface 129 of cam 128 on thecurved plate 124 fixed to the wheel 123; this locking-action takes placewhen the toothed art of the said wheel 123 is removed from t e toothedwheel 125. The tube can then be removed from the machine, that is to saydisplaced from the mandrel 135.

The manner in which the removal of the tube from the machine is effectedis as fol lows. Near the socket 134 the mandrel 135 is provided with aring 160, having a slot 161 situated in alinement with the slot 158which gives passage to the edge of the paper when the latter is fed tothe mandrel. The ring 160 is fixed to a support 162 (Figs. 7 and 9)fixed to the end of a rod 163 adapted to slide in suitable guides formedin the bearing 133. To the rod 163 is fixed an arm 164 (Fig. 8) carryingat its end a rod 165 adapted to rock through a small arc in a horizontalplane. One end of this rod is connected at 166 (Fig. 9) with a lever 167pivoted at 168 to a suitable support 169 mounted on the table 112.Beyond the pivot 168 the lever 167 is provided with a curved arm 170 towhich is-connected a spring 171. The arm 170 is adapted to be operatedby a cam 172 fixed to the shaft 120. During each revolution of saidshaft the cam 172 causes the arm 170, and the lever 167 to rock on thepivot 168, so that the said lever causes the rod 165 to rock on itssupport, the said rod having sufiicient play for this purpose. Therod'165 is thus displaced according to the are described by the pivot166 on the lever 167 and displaces, by means of the arm 164, the rod163, which moves in its guides and displaces, by means of the arm 162,the ring 160. By sliding along the mandrel the ring displaces the tubeformed. When the cam 172 has cleared the arm 170 of the lever 167 thespring 171 causes the said lever to return to the position shown in Fig.9, and thus to operate the rod 163 by means of the rod 165, and the arm164, so that the ring 160 is moved back to its normal position. In theabove description it has been shown that the gear controlling themandrel, the pasting and pressing-devices viously describer forms partof this mechan ism.

The table 112 is provided with arms 173 which support a dove-tail guide174 provided with slots 175. The latter allow of fixing to the guide, inany suitable position, vertical arms 176 supported by bolts 177 theheads of which are counter-sunk in the guide-way 179. The arms 176 carrya rack 17 8 projecting from the lane of the guide 17 4. Slides 180 and181 (Figs. 11, 12 and 13) are movable in the guide 174 and support, bymeans of bolts 182, a rack 183 situated in the same vertical plane asthe rack 178. The racks 178 and 183 mesh with a gear-wheel 184 mountedon an axle 185 fixed to an arm 186, to which a rod 188 is connected at187, the said rod 188 consisting of two parts connected with each otherby means of a bolt 189 which engages slots 190 in the two parts of saidrod. The effective length of the latter can thus be varied at will.

One end of the rod 188 extends into a radial slot 191 in a plate 192fixed to the end of a horizontal shaft 193 (Fig. 10) revoluble inbearings 194 supported by the plate 110 on the frame 109.- To the shaft193 is fixed a bevel-wheel 195 meshing with a bevel-wheel 196 which isfixed to the shaft 117 above the plate 110 and below the table 112. TheWheel 196 is provided with two toothed parts 197 and with two smootharts 198, so that during each revolution 0 the controlling shaft 117 theplate 192 is successively rotated, stopped, again rotated and againstopped. During its rotation the plate 192 o erates, by means of the rod188, the gearw eel 184, so that the latter rolls on the rack 17 8, andtransmits its longitudinal movement to the rack 183, which is guided inthe fixed guide 174 by means of the slides 180 and 181.

It will be understood that owing to the engagement ofthe rod 188 in theradial groove 191, and to the variable effective length of the said rod,in combination with the adjustability of the racks 178 and 183 withregard to the gear-wheel 184, the travel of the rack 183 can be variedwithin wide limits without exchanging or replacing any part of themechanism. The rack 183 controls the movement of the art which grips thecut paper and feeds the atter to the mandrel. For this urpose theslide181 is provided with an ang ar arm 200 having a slot 201 into whicha cylindrical or squared socket 203 (Fig. 13) is adjustably fixed bymeans of a bolt 202, said socket supporting a vertical axle 204 to whicha gear-wheel 205 is fixed above the socket 203 and above a squaredportion of the said axle. To the latter is fixed a vertical support 206provided with an arm 207 which terminates in a socket 208 into whichengages the rod 209 of a gripper 210 arranged at right angles withregard to the said rod. To the support 206 is pivoted at 211, an arm 212terminating in a socket 213 similar to the socket 208. A spring 215 isattached to an extension 214 of this arm and to the bent end 216 of thesupport 206. Into the socket 213 engages the rod 217 of a gripper 218placed at right angles with regard to the said rod and situated in theplane of the lower fixed gripper 210. The gripper 218 is provided with apad 219 of india rubber or other suitable material which normally bearson the gri per 210. In a lug 220 of the support 206 Fig. 11) is pivotedat 221 a hook 222 under the action of a spring 223 and adapted to engagewith its nose 224 a projection 225 on the extension 214 when the latteris lowered to a sufficient extent, for the purpose of opening thegrippers that is to say, the movement of the gripper 218 away from thefixed gripper 210. The hook 222 is also provided with a tail carrying arod 226 adapted to make contact with a suitable abutment so that thehook is rotated on its ivot 221 to cause the release of the nose 224from the projection 225. When the extension 214 is lowered to permit thenose 224 to engage the projection 225, the gripper is opened by theraising of the part 218, but on the contrary, when pressure is exertedon the rod 226, the hook 222 is rotated in the reverse direction and isdisengaged from said projection 225, whereupon the gripper 218 islowered onto the fixed gripper 210 by the action of the spring 215. Thisopening and closing of the grippers 210 and 218 is effected by means ofthe levers 227 and 228 (Fig. 9) the lever 227 being pivoted on a support229 (Fig. 9) mounted on the table 112 and serving for opening thegripper when the latter has introduced the aper into the mandrel. Oneend 2300f said ever 227 bears on a cam 231 mounted on the shaft 120 andthe other end carries an adjustable support 232, in which is mounted arod 233 the position of which can be varied by the rotation of the saidsupport 232 on the end of the lever 227 The effective length of the rod233 can be adjusted as desired by means of a set screw 234 so that onthe oscillation of the lever 227 under the action of the cam 231 the endof said rod can be caused to act on the extension 214 of the lever 213of the upper gripper 218 (Fig. 11) and depress said extension su cientlyto allow the nose 224 of the hook 222 to engage the rojection 225previously men-- tioned. The ever 228 mounted at the other end of thetable 112 in a support 235 is adapted to close the gripper at the momentwhen it must grip the paper, as will be hereinafter explained. For thispurpose the said lever 228 is provided at its end with a small axiallyrotatable support 236 similar to the'support 232 above mentioned andcarrying a rod 237 of adjustable length. This rod can be adjusted insuch a manner as to be able to engage the tail rod 226 (Fig. 11) of thehook 222, when (after displacement of the support 206 with the rack 183)the hook 222 has cleared the end of the rod 237 which has at this momentbeen raised by the action of a cam 238 on the end 239 of the lever 228said cam being on the shaft 120. Consequently at the moment when thegripper is displaced longitudinally with regard to the slide 174 by therotation of the plate 192, the cam 238 depresses the end 239 of thelever 228 and raises the rod 237 to allow the passage of the grippermechanism. As soon as this said mechanism has passed, the cam 238 leavesthe end 2390f the lever 228, and the latter is then quickly returned bythe action of a spring 240 (I? ig. 8) so that the suitably adjusted rod237 is caused to make contact with the rod 226 of the hook 222 and causethe latter to rotate for the purpose of disengaging its nose 224 fromthe projection 225 and thus release the upper gripper218 whichis thuslowered on to the lower gripper 210. It will thus be understood, that,when the socket 203 travels with the rack 183 the gripper is displacedin a direction parallel to the mandrel 135 and is opened when it is atthe end of its travel near the point of the mandrel; it then remainsopen during the next period during which it advances towards the paperwhereupon it is closed at the moment when the lever 228 acts on the rod226 of the hook 222, and grips the paper carrying it along in itsfollowing rearward movement and at the same time introducing its edgeinto the groove 158 in the mandrel until the lever 227 acting on theextension 214 again opens the gripper. The paper is thus released andcarried along by the mandrel to which rotary motion has been imparted inthe manner above described In the previous description of the action ofthe gripper only the longitudinal displacement of said gripper parallelto the axis of the mandrel 135 has been dealt with; this movement issuflicient when the gripper can introduce the paper into the groove inthe mandrel by a simple rectilinear displacement, but this movement isinsufficient when the paper has to be introduced into the mandrel by anedge forming for example a right angle with regard to the direction ofthe mandrel as is for instance the case with the rectangular piece ofpaper 93 for the formation of cylin drical tubes under the conditionsshown in I ig. 1. In this case the paper must be intro duced into themandrel 135 by the edge produced by the action of the knife 89 and it isconsequently necessary to cause the paper to execute a rotary movementin a horizontal plane. This movement is produced by a correspondingrotation of the gripper by the action of the gear wheel 205 mounted onthe vertical axle 204 integral with the support 206.

On the rectilinear movement of the socket 203 in which the axle 204revolves, the gear wheel 205 engages (at a predetermined moment in thetravel of the socket 203), a rack 241 adjustably mounted by means of aslot 242 and bolt 243 on an angular arm 244 also adjustably mounted bymeans of a slot and bolt 245 246 respectively on the end of a bar 247forming a prolongation of the slide 174 and adjustably mounted on thelatter by means of a slot 248 and bolts 249. to this arrangement, whenthe gear wheel 205 engages the rack 241 the former is given a partialrotation which causes the axle 204 to revolve on its vertical axis andconsequently also the support 206 of the gripper. The latter can,therefore, assume a determined angular position, according to therotation of the gear wheel 205 by its engagement with the rack 241. Ifthe work to be effected requires the gripper, after having made adetermined rotation of for instance one quarter revolution, to alsocarry out a certain rectilinear movement, this result can be obtained byadjustment of the rack 241 and by combining with the arm 247 a guide 250(Figs. 12 and 13) against which abuts the squared portion of the axle204, below the wheel 205, so that said axle 204 is held in positionafter the gear wheel 205 has been disengaged from the rack 241. Fig. 1shows diagrammatically the action of this arrangement relatively to thetube forming mechanism represented by 27. The support 206 is providedwith a rod 251 to which is connected a spring 252 attached at anyconvenient part of the fixed socket 203. tion of the support 206, by theengagement of the gear wheel 205 with the rack 241 as described, thesaid spring 252 is tensioned and tends to pull back the rod 251 andconsequently return the support 206 to its normal position, that is tosay, that in which the gripper is parallel to the axis of the mandrel.In order to insure the gripper being held in said position the lower endof the axle 204 carries a collar 253 to which is connected a rod 254forming an abutment and normally bearing against the lateral surface ofthe slide 174. Owing to this construction it is evident that on rotationof the support 206 the abutment rod 254 moves away from the surface ofthe slide 174, against which it is automatically returned by the actionof the spring 252when the latter acts to return the gripper into itsnormal position after the gear wheel 205 has left the rack 241.

It should be stated that the adjustable mounting of the sleeve 203 inthe slot 201 of O11 rota-.

Owing the arm 200 combined with the displacement of the rods 209 and 217carrying the grippers in their respective sockets 208 and 213 permits ofgiving said grippers any determined position with regard to the mandrelsand with regard to the edge of the paper to be gripped and introducedinto the mandrels. The rack 241 can also be adjusted in such a manner asto occupy a position corresponding to that of the gear wheel 205, thatis to say, according to the position of the socket 203 on the support200 and also in such .a manner as to effect the rotation of the grippertowards the end of its course at any convenient moment when desired. Thefirst adjustment can be obtained by displacing the angular arm 244 onthe bar 247 by means of practice.

the slot and bolt 245 and. 246 and the second by varying the position ofthe rack 241 on the arm 244 by means of the slot and bolt 242 and 243 orby longitudinally displacing the bar 247 on the slide 174 by means ofthe slot 248 and bolts 249.

It will be seen from the above description, that the whole of themechanism represented in Figs. 11, 12 and 13 for feeding the paper tothe mandrel is carried by the table 112 and forms as it were a completetube forming mechanism adapted to be given any predetermined angularposition with regard to the driving shaft 107 the direction of rotationof which must obviously always remain the same since it is determined bythe direction of rotation of the main driving shaft 17.

As shown diagrammatically in Figs. 1 and 18 each machine usuallycomprises two complete forming mechanisms. It is owing to theadjustability of these complete forming mechanisms which may be givenany position desired with regard to the feed mechanism that the machinecan be adapted to the manufacture of tubes of any shape used in Not onlycan each frame 109 carrying the table 112 be arranged at any suit ablepart of the table 2 by simply manipulating the bolts in the slots 3 insaid table, but the rotary table 112 can also be given any angularposition with regard to the longitudinal axis of the machine in such amanner as to permit the introduction of the paper into the mandrel by asimple rectilinear movement of the gripper combined, in some cases, witha rotation of said gripper by the action of gear wheel 205 and rack 241.Fig. 1 shows in this respect one of the most complicated cases to be metwith in practice, viz: that of the manufacture of two cylindrical tubesby means of paper with thinned edges, this paper being cut into tworectangles 93 and 94 cut by the knives 89 and 91, these rectangleshaving to be introduced into the mandrels by the edge out by thelongitudinal knife 89 so that the thinned edge 34 of the paper afterwinding, is outside the tube for the purpose of being pasted. Aspreviously explained the cutting device 32 isprovided with supports ofthe kind shown in Figs. 14 and 15, the arm 64 having the downwardly bentpart 87 which permits the passage of the gripper 210, 218, when it isdisplaced by its driving mechanism. For producing this kind of tube, asshown in Fig. 1 one of the forming mechanisms28 is arranged in such amanner that the gripper can seize the paper rectangle 94 and introduceit in the mandrel 135 by a simple rectilinear movement. The otherforming mechanism shown diagrammatically at 27 must, on the contrary,feed the paper to the mandrel firstly by a rectilinear displacementfollowed by a relation of the gripper and then by a second rectilinearmovement. For this purpose the parts of the gripper together with theposition of the rack 241 and of the guide 250 are so adjusted that atthe end of its travel the gripper can be caused to occupy the positionshown in dotted lines at 255, in Fig. 1, the gripper in this caseseizing the paper at the desired distance from its edge out by the knife89. When the gripper commences its rearward movement for taking thepaper to the mandrel, said gripper is first moved parallel to itself,the squared portion a of the axle 204 (Fig. 13) abutting against theguide 250 until at the moment when the gear wheel 205 engages the rack241, said axle is rotated and the squared portion leaves at this momentthe guide 250. Owing to the action of the rack 241 the gripper thenpasses from the position shown at 256 in dotted lines (Fig. 1) into theposition shown in full lines in 257. In this position the gear wheel 205is disen gaged from the rack, 241, and the gripper is held with itsparts 210, and 218 in a position parallel to the axis of the mandrel135; the paper beingthen introduced into the mandrel during thecontinued rectilinear movement of the gripper.

By referring to Fig. 18 it will be seen how the same machine can beadapted to the production of absolutely different tubes for instance tothe production of tubes formed of triangular pieces of paper as shown at95 and 96. In this case the two forming mechanisms 27, 28 are arrangedsymmetrically with regard to the longitudinal axis of the machine andthe rotation of the tables 112 on the plates 110 by the displacement ofthe table supports in the slots 111 permits of giving the mandrel anynecessary angular position according to the inclination of the line ofout produced by the knife 89 and according to the edge by which thetriangular pieces of paper have to be introduced into the mandrels. Inthis case the gripper is only given rectilinear movement and the rack241 can be removed from its support or placed in such a position that itis not engaged by the gear wheel 205 during the reciprocating movementof the gripper. It is
